Definitions

  • the present invention relates to mechanisms for extracting water from a web of material, and, more particularly, from a fibrous web being processed into a paper product on a papermaking machine.
  • the present invention is an impermeable belt designed for use on a long nip press on a papermaking machine, and a method for constructing the impermeable belt.
  • a fibrous web is formed on a forming wire by depositing a fibrous slurry thereon.
  • a large amount of water is drained from the slurry during this process, after which the newly formed web, left behind on top of the forming wire, proceeds to a press section.
  • the press section includes a series of press nips, in which the fibrous web is subjected to compressive forces designed to remove additional water therefrom.
  • the web finally proceeds to a drying section, which includes heated dryer drums around which the web is directed. The heated dryer drums reduce the water content of the web to a desirable level through evaporation, thereby completing the manufacture of a paper product.
  • press sections have included a series of nips formed by pairs of adjacent cylindrical press rollers.
  • long press nips are so called because they have a greater extent in the longitudinal, or machine, direction than those formed by pairs of adjacent rollers. The longer the web can be subjected to pressure in the nip, the more water can be removed there, and, consequently, the less will remain to be removed through evaporation in the dryer section. This is accomplished in a long press nip by virtue of the fact that any given portion of the fibrous web takes a longer time to pass through the nip.
  • the present invention relates to long nip presses of the shoe type.
  • the nip is formed between a cylindrical press roller and an arcuate pressure shoe.
  • the latter has a cylindrically concave surface having a radius of curvature close to that of the cylindrical press roller.
  • a nip is formed which can be five to ten times longer in the longitudinal, or machine, direction than one formed between two press rollers. This increases the so-called dwell time of the fibrous web in the long nip while maintaining the same level of pressure per square inch pressing force used in a two-roller press.
  • the result of him new long nip technology has been a dramatic increase in dewatering of the fibrous web in the long nip when compared to conventional nips on paper machines.
  • a long nip press of the shoe type requires a special belt, such as that shown in U.S. Patent No. 4,946,731 to Dutt.
  • This belt is designed to protect the press fabric supporting, carrying, and dewatering the fibrous web from the accelerated wear that would result from direct, sliding contact over the stationary pressure shoe.
  • Such a belt must be made with a smooth impervious surface that rides, or slides, over the stationary shoe on a lubricating film of oil. The belt moves through the nip at roughly the same speed as the press fabric thereby subjecting the press fabric to minimal amounts of rubbing against stationary components of the press.
  • a typical configuration for a long nip press involves the use of two press fabrics.
  • the components in the nip can be listed in the following sequence: a grooved cylindrical press roller, a first press fabric, the fibrous web or nascent paper sheet, a second press fabric, the special belt, the lubricating film, and the arcuate pressure shoe.
  • the components in the nip would be listed in the following sequence: a smooth cylindrical press roller, the fibrous web or nascent paper sheet, the press fabric, the special belt, the lubricating film, and the arcuate pressure shoe. As implied by this sequence, the fibrous web actually contacts the cylindrical press roller in a single-felted long nip press.
  • the water pressed from the fibrous web can pass into either of the two press fabrics, as well as into the grooves provided in the cylindrical press roller.
  • the single-felted long nip press two of these sinks for water storage have been eliminated. There is only one felt and, because the fibrous web contacts the cylindrical press roller directly, this roller must have a smooth surface. Clearly, this loss of temporary water storage space must be made up in another fashion, because it is absolutely mandatory that voids be provided in the nip of the press, so that water pressed from the paper sheet in a single-felted long nip press will have a place to go.
  • Canadian Patent No. 1,190,779 shows a long nip press belt having voids on the felt side. These voids arise from the weave pattern of the base fabric and the absence of impregnation on the felt side of the belt, and provide a place into which liquid can be transferred during passage of the fibrous web, press fabric, and special belt through the nip.
  • the grooves may collapse under the elevated compression to which the belt is subjected in the nip.
  • an endless base fabric must be provided in the dimensions required for a specific long nip press. That is to say, the endless base fabric must have a width, measured transversely thereacross, equal to that of the long nip press, and a length, measured longitudinally therearound, sufficient to permit the belt to be trained about all the tension and guide rolls on the press.
  • each long nip press belt is to a large extent a unique item, making it difficult to streamline the process whereby belts of different size are manufactured.
  • the present invention includes a method for manufacturing long nip press belts of varying transverse and longitudinal dimensions, which does not require the provision of an endless base fabric in the dimensions required for a specific long nip press.
  • long nip press belts may be readily and quickly manufactured for a variety of different presses on a single apparatus with common materials.
  • the present invention also includes a belt made in accordance with the method.
  • the belt in addition to its ease of manufacture, is also less susceptible to delamination and collapse of its grooves than the belts of the prior art.
  • the long nip press belt of the present invention is constructed by winding an elongated strip around and between a pair of process rolls to produce a closed helix having a desired length, as measured longitudinally around the closed helix, and a desired width, as measured transversely across the closed helix.
  • the elongated strip which has a constant width and a uniform thickness, includes a reinforcing web, which may be a narrow strip of woven fabric, having a first side and a second side.
  • the first side is coated with a first coating of a first polymeric resin, this first coating being uniformly smooth.
  • the second side of the reinforcing web is coated with a second coating of a second polymeric resin, which has a hardness value greater than that of the first,polymeric resin.
  • the second coating has at least one groove in a longitudinal direction along the elongated strip. The thickness of the elongated strip, as measured from the surface formed by the first coating to the outer surface of the land areas separating the grooves in the second coating, is uniform.
  • the present belt is manufactured using a pair of process rolls. These process rolls are rotatable about their respective axes, and are situated such that their axes are parallel to one another. The distance separating the process rolls is set and determines the length of the belt, as measured longitudinally therearound, to be manufactured.
  • the manufacture of a belt is begun by extending the elongated strip from one of the process rolls toward the other process roll, around that other process roll, and back to the first roll, to form a first coil of a closed helix which becomes the final belt.
  • the uniformly smooth first coating on the elongated strip faces the process rolls and ultimately forms the inner surface of the closed helix.
  • manufacture proceeds by rotating the process rolls in a common direction to produce subsequent coils by winding the elongated strip onto the process rolls, while continuously joining the edge of the elongated strip where just being wound onto the process rolls to that which has already been wound thereabout.
  • the elongated strip not yet wound onto the process rolls and no longer required, is cut, leaving the complete closed helix of desired length and width on the process rolls. It is then removed therefrom to provide a belt suitable for use as a long nip press belt on a papermachine.
  • Figure 1 is a side elevational view of a long press nip for which the belt of the present invention is designed.
  • Figure 2 is a partially sectioned front view of the press nip shown in Figure 1.
  • Figure 3 is a plan view of the belt of the present invention.
  • Figure 4 illustrates the method by which the belt of the present invention may be manufactured.
  • Figure 5 is a cross section of the elongated strip having edges which form a buttress joint when wound into the form of a closed helix to produce the present belt.
  • Figure 6 is a cross section similar to that showing Figure 5 wherein the elongated strip has edges which form a skived joint.
  • Figure 7 is a cross section similar to those shown in Figures 6 and 7 wherein the elongated strip has edges which form an interlock joint.
  • a single-felted long nip press for dewatering a fibrous web being processed into a paper product on a paper machine is shown in Figures 1 and 2.
  • the press nip 10 is defined by a smooth cylindrical press roller 12, an arcuate pressure shoe 14, and a belt 16 of the present invention arranged such that it bears against the surface of the cylindrical press roller 12.
  • the arcuate pressure shoe 14 has about the same radius of curvature as the cylindrical press roller 12.
  • the distance between the cylindrical press roller 12 and the arcuate pressure shoe 14 may be adjusted by means of conventional hydraulic or mechanical apparatus, which is not shown, connected to rod 18 pivotally secured to arcuate pressure shoe 14.
  • the rod 18 may also be actuated to apply the desired pressure to the arcuate pressure shoe 14.
  • the cylindrical press roller 12 and arcuate pressure shoe 14 described above and shown in Figures 1 and 2 are conventional in the art.
  • FIGS 1 and 2 Also shown in Figures 1 and 2 are a papermaker's wet press fabric 15 and a fibrous web 17 being processed into a paper sheet.
  • the motions of the belt 16, press fabric 15, fibrous web 17 and cylindrical press roller 12 are as indicated by the arrows in Figure 1.
  • a plan view of the belt 16 of the present invention is provided in Figure 3. It has an outer surface 19 and an inner surface 20.
  • the outer surface 19 is characterized by a plurality of grooves 22, while the inner surface 20 is uniformly smooth. Grooves 22 spiral in a substantially longitudinal direction around the length of the belt by virtue of the helical fashion in which the belt is constructed.
  • the apparatus 30 includes a first process roll 32 and a second process roll 34, each of which is rotatable around its longitudinal axis.
  • the first process roll 32 and the second process roll 34 are parallel to one another, and are separated by a distance, which will determine the overall length of the belt to be manufactured thereon, as measured longitudinally around the belt.
  • the belt is manufactured on apparatus 30 from an elongated strip 36, the details of which will be provided below during the discussion regarding Figures 5 through 7.
  • the beginning of the elongated strip 36 is extended in a taut condition from the first process roll 32 toward the second process roll 34, around the second process roll 34, and back to the first process roll 32 forming a first coil of a closed helix 38.
  • the beginning of the elongated strip 36 is joined to the elongated strip 36 just being wound onto the first process roll 32 by a suitable adhesive at point 40. This adhesive may be heat-activated.
  • subsequent coils of closed helix 38 are produced by rotating first process roll 32 and second process roll 34 in a common direction as indicated by the arrows in Figure 4, while feeding the elongated strip 36 onto the first process roll 32.
  • the elongated strip 36 being freshly wound onto the first process roll 32 is continuously joined to that already on the first process roll 32 and the second process roll 34 by a suitable adhesive to produce additional coils of closed helix 38.
  • the closed helix 38 has a desired width, as measured axially along the first process roll 32 or the second process roll 34. At that point, the elongated strip 36 not yet wound onto the first process roll 32 and the second process roll is cut, and the closed helix 38 produced therefrom is removed from the first process roll 32 and the second process roll 34 to provide the belt 16 of the present invention.
  • an endless base fabric is not a part of the belt 16 of the present invention, nor does such a base fabric need to be coated with a polymeric resin on one or both sides, in contrast to long nip press belts of the prior art.
  • the method to produce the present belt is quite versatile and adaptable to the production of belts of a variety of longitudinal and transverse dimensions, since the same apparatus 30 and elongated strip 36 are always used. That is to say, the manufacturer, by practicing the present invention, need no longer produce an endless base fabric of appropriate width and length as a first step toward the manufacture of a belt for a given papermachine.
  • the manufacturer need only set the first process roll 32 and the second process roll 34 the appropriate distance apart, to determine the length of the belt 16, and wind the elongated strip 36 onto the first process roll 32 and the second process roll 34 until the closed helix 38 has reached the desired width.
  • the elongated strip first comprises a reinforcing web 50, which may be a narrow strip of woven fabric. Monofilament yarns extruded from any of the synthetic polymeric resins commonly used to manufacture yarns for papermachine fabrics are appropriate for use in weaving the required narrow strip of woven fabric for use as reinforcing web 50. Polyamide and polyester yarns are but two examples.
  • the elongated strip 36 is of constant width and uniform thickness. The elongated strip 36 has a first edge 52 and a second edge 54.
  • the reinforcing web 50 has two sides, one of which is coated with a first coating 56 of a first polymeric resin.
  • the first coating 56 is uniformly smooth, and, during the production of belt 16, forms the inner surface 20 thereof.
  • the first coating 56 and the second coating 58 cooperate to completely impregnate the reinforcing web 50, thereby rendering the elongated strip 36 impermeable to fluids, such as lubricating oil and water.
  • the other side of reinforcing web 50 is coated with a second polymeric resin.
  • the second polymeric resin has a hardness value greater than that of the first polymeric resin, so that the longitudinal grooves 60 provided in the second coating 58 may less readily collapse, when belt 16 produced from elongated strip 36 is in a press nip.
  • the thickness of elongated strip 36, as measured from the surface of the first coating 56 to the tops of the land areas 62 between grooves 60 in the second coating 58, is uniform.
  • the grooves 22 in belt 16 in Figure 3 spiral in a substantially longitudinal direction thereabout, because elongated strip 36, is wound into the form of closed helix 38 in Figure 4 to produce belt 16.
  • the first coating 56 of a first polymeric resin which forms the inner surface 20 of belt 16 on its smooth or shoe side, may have a hardness value of 88 to 90 on the Shore A scale, or of 63 to 68 on the Shore C scale.
  • the second coating 58 of a second polymeric resin which has grooves 22 and forms the outer surface 19 of belt 16 on its grooved or felt side, may have a hardness value of 96 to 99 on the Shore A scale, or of 83 to 90 on the Shore C scale.
  • the elongated strip 36 may be manufactured by a process of composite extrusion, such as that used to manufacture some belting products. Elongated strip 36 may be from 1 inch to 6 inches wide, and 0.300 inch thick. Synthetic polymeric resins, such as 100% solid polyurethane resins, may be used in the composite extrusion process to provide the first coating 56 and the second coating 58.
  • first edge 52 and second edge 54 of elongated strip 36 are formed so as to cooperativaly provide a buttress joint 64 when elongated strip 36 coils are overlapped in winding closed helix 38.
  • the interface 66 is wider than the thickness of elongated strip 36, and, when coated with an adhesive, provides a more effective bonding between successive coils of the closed helix 38.
  • Figures 6 and 7 show two additional joints for elongated strip coils.
  • a skived joint 70 is formed by first edge 72 and second edge 74 of elongated strip 76.
  • elongated strip 76 is of the same construction as elongated strip 36.
  • an interlock joint 80 is shown in Figure 7, and is formed by first edge 82 and second edge 84 of elongated strip 86.
  • interlock joint 80 provides for a certain amount of geometrical retention between the first edge 82 and the second edge 84 of successive coils formed by elongated strip 86 to supplement that provided by the adhesive used to join the coils together.
  • a urethane-based adhesive may be used to secure adjacent coils of closed helix 38 to one another, particularly where the elongated strip 36 includes polyurethane resins, to ensure that finished belt 22 is impermeable.
  • the present invention renders it no longer necessary to cut spiral or annular grooves in the coating on one side of an endless base fabric by mechanical means to produce same for a long nip press, as the elongated strip used to assemble the belt already is provided with the required grooves.
  • the belts 16 of the present invention there would preferably be six to eight grooves 22 per inch as determined by counting across the belt 16 in a direction transverse to the grooves 22.
  • the depth of the grooves 22 would fall in the approximate range of from 0.060 inch to 0.100 inch; the width of the grooves 22 would fall in the approximate range of from 0.020 inch to 0.040 inch.
